The good news is that a working teleportation device already exists. The bad news is that it won’t work for you if you happen to be bigger than a rubidium atom—but scientists are toiling away to fix that. As physicist Michio Kaku noted last year in DISCOVER, we could be teleporting things as big as a virus within a few decades, which means we would be ready teleport a person around the 23rd century, just in time for the predicted construction date of Captain Kirk’s Enterprise.
